RFID credit card modded into Hello Kitty Pez Dispenser

Windell Oskay of Evil Mad Scientist Laboratories removed the RFID circuit in a MasterCard PayPass and placed it into a Hello Kitty Pez dispenser. He calls it "Hello Credit."
One interesting thing is that the circuit board is incredibly thin -- approximately 1/4 the thickness of standard 1/16" circuit boards, which happens to be pretty close to the thickness of a standard credit card. It's flexible and fairly translucent. You do need to be a little bit careful because ceramic capacitors (like the ones on this board) have a tendency to break if you bend the board that they are soldered to.

Of course, we can now give our RFID element any kind of a case mod that we see fit. One thing that would be easy to do is just to embed it in the side of a wallet. You could also embed it in any one of the millions of things that have become USB thumb drives in the last few years.

  1. The best part is that if you line the PEZ dispenser with foil, you won’t be getting your RFID scammed.

  2. It strikes me that if you made the base out of (or lined with) metal, it would also deter snooping. Pop open the dispenser to use.
